WINDOW-SHADE.

SPECIFICATION forming part of Letters Patent No. 727,560,dated May 5, 1903.

Original application filed August 20, 1900. Serial No. 27,400. Divided and this application filed Angust19, 1901. Serial No- 72,601- (No model.)

To etZZ whom it may concern:

Be it known that I, PLATO G. EMERY, a citizen of the United States, residing at Chicago, in the county of Cook and State of'lllinois,

.have invented certain new and useful Imguiding devices at the ends of the shade-stick,. so that they-can be readily and easily with-' drawn from their grooves and the shade disengaged from the window-frame for cleaning and other purposes.

Another important object of the invention is to provide means for adjusting the guiding devices to operate in the grooves of the'win; dow-frame yieldingly with sufiicient friction and without binding and at the same time provide for quickly withdrawing the guiding devices from the grooves, and another object of the invention is to provide. stops at the ends of the stick to prevent complete tilting thereof and at the same time permit a yielding adjustment of the guiding devices to allow for slight variations in the width of the window-frame. 4

The invention has other objects 'in view, which will appear hereinafter in the detailed description, reference being hadto the accompanying drawings, in which Figure 1 illustrates a window-frame pro.- vided with a shade embodying my invention. Fig. 2 is a view partly in section, showing an adjustable stop device at-oneend and a releasing device at .the other end of the shadestick. Figs. 3, 4, and 5 are views partly in section, showing diflerent forms of'lhe invention in which the releasing device is combined with the adjustable stop device. Fig. 6 is a detailed view of the adjusting-sleeve. Fig. 7 is a detailed view of a supplemental guiding-sleeve to proventthd head 96 the handle from binding against the tubular shadestick. Fig. 8 is a detailed view of ope handle. Fig. 9 is a detailed view of the disengagingsleeve. Fig." 10 shows the sleeve 38 constructed for use as an adjusting device and also as a releasing device. Fig. 11 shows one end of the torsion-spring 17 attached to. the

main part of the stick adjacent to thesleeve and the otherend connected with the sleeve itself.

The invention consists, essentially, of

- shade-holding means-comprising endwise-adjnstable stop devices for holding the guideshoes in the grooves of the window-frame and means for permitting one or both of these guide-shoes to be retracted for the purpose of withdrawing the guide-shoes from engage ment with the frame and out of the grooves. InFig. 2 of th drawings I have shown a shadest'ick provided with an adjustable stop at one end and with a spring-actuated. releasing device at -the other end, which normally acts as a stop for the guide-shoe, and in Figs. 3 and 4. I have shown an adjustable stop combined with the releasing device at one end of thestick, and in Fig. 5 I have shown the adjnstable stop device constructed like the releas ing device shown in Fig. 2, except that it has a screw-threaded instead of a spring adjustment. ,It will be understood at the outset, therefore, that the adjustable stop device and the releasing device may be used independently of each other or together, or they can be combined in'one device. i I do not claim, broadly, herein a yielding stop device, as this'is claimed in. my Patent No.7l6,832,granted December 23,1902; nor do I claim, broadly, herein a f riction-foot having a movement independent of the guide-shoe, as this is-claimed in a concurrent application filed August 19, 1901, Serial No. 72,602,"

Referring to the drawings, in which like numerals of reference denote corresponding parts in the several figures, 10 designates the curtain of my improved window-shade,which is attached to the spring roller 11 and provided at its lower end with a tubular shadestick 12, carrying guiding devices 13 at its ends,which are arranged to travel. in the vertical guide-grooves 12 in'the" window-frame. In the preferred construction of my was ent invention, as illustrated in Fig. '2, I employ a shade stick provided with a releasing device at one end, consisting of a sleeve 14, forming a. continuation of the stick and having oppositely-arranged notches or recesses at its outer end of sufficient width to receive the guide-shoe 16 when alined therewith. the notches or recesses will be in a plane substantially transverse to the guide-shoe by means of a torsion-spring 17, which has one of its ends set in the guide-shoe, shown at 18, and its other end passed through a slot 19 in the flange 20 on the end of the sleeve, Fig: 9. The torsion-spring may be otherwise arranged to hold the sleeve in substantially the position shown in Fig. 2-- as, for instance, one end 17 thereof could be attached to the main part of the stick adjacent to the sleeve and the other end 17" could be attached to the sleeve itself, as shownin Fig. 11. It will thu be observed that the sleeve is normally held with its notches or recesses out of alinement with the guide-shoe; but when it is desired to move the guide-shoe longitudinally with relation to the stick for the purpose of -withdrawing -the guide-shoe from its groove the sleeve is turned against the tension of its spring until the notches or recesses are in alinement with the guide-shoe, so that the latter may enter said notches or recesses, which should be of sufficient depth to permit the guide-shoe to be withdrawn from the groove.

The guiding devices carried on the ends of the shade-stick may be of any'desi'r'ed construction, and I do not restrict'myse'lf to the particular form illustrated, which consists of anelongated guide-shoe 16, provided with rollers 21 at its ends and having a centrally disposed spring-pressed friction-foot 22. The guide-shoe is preferably provided with ahollow shank 23, which is arranged Within the end of the shade-stick, and the friction-foot is also provided with a hollow shank 24, through the end of which passesa rod 25, which extends approximately to the-middle of the shade-stick and carries the pinchhandle 26, which projects through a slot 27 in the stick. The handle 26, Fig. 8, is provided with a round head 28 and a neck 29, and the slot 27 is ot'sufiicient width to permit the neck of the handle to slide freely therein.

The head of the handle is inserted in the slot and then turned at right angles into operative position, and it is provided with a screw-threaded opening 30 to receive the threaded end of the rod 25, the head 31 of said rod having a bearing against a shoulder 32 within the bore of the shank of the frictionfoot. To prevcpt the head of the handle from binding in the shade-stick and to facilitate the movement thereof, I provide'a sleeve 33, Fig. 7, which is arranged on the bud ot' the rod 25 and over the head of the handle and provided with a slot 34 in its side to receive the neck of the handle and having an open- The sleeve is normally held so that.

are preferably constructed alike it will be readily understood that when the handles 26 are pressed toward each other or pinched the friction-feet will be withdrawn against the tension of their springs out of engagement with the back wall of the grooves, so thatthe shade may be raised or lowered, but without beingremoved from the grooves or affecting the guide-shoes.

In Fig. 21 have shown an adjustment for the shade-stick in the form of a sleeve 38,

having a screwJahreaded connection at 39 with the end of the shade-stick and forming a continuation thereof. In this construction the sleeve 38 forms a stop device at one end of the stick and the releasing device forms a stopdevice at the other end, and the spring 17 holds the sleeve 38 yieldingly in engagement with the guide-shoe.

In Figs. 3, 4, and 5 I have shown a releasing device combined with the adjustable stop device and a spring 40 arranged between the stop 37 and the end of the shank 23 of the guide-shoe. In the construction of Fig. 3 the sleeve 38 is arranged loosely on the shank 23 of the guide-shoe and provided with ascrewthreaded connection at 39 with the end of the shade-stick, and it also has an annular finger-piece 41 at its outer end to facilitate its adjustment. This sleeve is normally adjusted out of contact witlf the guide-shoe; but the latter abuts against the sleeve when the handles are pinched and is prevented thereby from being accidentally withdrawn from the groove. In the construction of Fig. 4 the shank 23 of the guide'shoe is screw-threaded and a nut 42 is arranged thereon between the guide-shoe and an end of the shade-stick, by means of which the adjustment is effected. In Fig.5 I have shown a spring 40 for throwing the guide-shoe into normal operative position and an adjusting device consisting of a sleeve 43, substantially similar to the sleeve 14, shown in Fig. 2, except that it has a screw-threaded connection at 4i with the end of the shade stick instead of the torsionspring. In this construction the releasing device is operated in precisely the same manner as in the construction of Fig.2, and it also performs its function as an adjustable stop device substantially in every respect similar to the adjustable stop devioeprovided by the sleeve 38 in Figs. 2 and 3. The sleeve 38 in Figs. 2 and Sean be made to correspond to the sleeve 43 in Fig. 5 by simply providing it with the notches or recesses 15, as shown in Fig. it), and when so constructed this sleeve ployed as an adjusting device and also as a releasing device.

My invention provides shade holding means of novel construction which are adapt ed to hold the curtain against the tension of the spring-roller and at the same time permit of its being readily adjusted without liability of the guiding devices becoming withdrawn from the grooves, which is of especial importanceiu this art, as the shades are ma nipulated more or less carelessly, and it is desirable to maintain the guiding devices in their proper operative arrangement in the grooves at all times. Whenever it is desired toclean the curtain or to remove the guiding devices from the groove and release the curtain from its guided arrangement, the guiding devices are allowed to enter the notches or recesses at the end of the stick, which enables the stick'to be tilted sufficiently to withdraw both of the guiding devices from the grooves, and in this connection the invention consists, broadly, of a shade-stick provided with notches or recesses at its end and a guiding device carried by the shade-stick and adapted to enter said notches or recesses.

The notch or recess in the sleeve 14 will be referred toin the claimssimplyasanotch, and it will beunderstood as comprgh'ending any construction of the sleeve which will permit the withdrawal of the guiding devices in the manner contemplated by the invention. Having thus fully described my'invention, what I claim, and desire to secure by Letters Patent, is-
